MACHINE FOR MAKING METAL SPO'UTS AND TUBES.

Application filed July 16,

T aZZ whom it may concern:

Be it known that I, Aoeus'r THoMsnN, a citizen of the United States, anda resident of the borough of Queens, Glendale, Long island, in thecounty of Queens andState of New York, (whose post-office address is 2331- Edison Place, Glendale, Long Island) have invented new and usefulImprovements in Machines for Making Metal Spouts and Tubes, of which thefollowing is a full, clear, and exact description.

The present invention relates particularly to machinery formanufacturing the end pieces or shapers for spouts. These spouts mayhave various uses. One particular use is in conjunction with adecorating gun for confectioners use, by which ornamentation is placedupon cakes or similar articles. Other spouts, such as required for oilcans and similar devices, are also formed by this machine. I

Among the principal objects which the present invention has in View are:To impart more perfect shape than heretofore to the spoutformingmembers; to simplify the construction of the spout; to diminish the timerequired for the construction; to increase the scope of usefulness inmachines of the character mentioned; and to permit rapid and simplealteration in the shapes of the spouts formed thereby.

Description.

As seen in the drawings, and particularly by reference to Figures 10 and9 thereof, the blank A shown in the former figure is curled about ashaping mandrel to be manually stripped therefrom as the spout Bdisclosed in the latter of the said figures. The shaping or curling ofthe blank to the shape shown in Figure 9 is primarily accomplished bythe smoothing blades 16 which are adjustably secured by set screws 17 onsliding plates 18. As shown best in Figure 4 of the drawings, there aretwo plates 18, which plates are guided in slots provided in the swingingframes 19. There are two frames 19, each being independently pivotallymounted on the shank 20 of the mandrel 15' and on the end of a laymandrel 21. The mandrels 15 and 21 are held stationarily in heads 22 atthe upper ends of standards 23. The standards 23 are made secureto thebase plate 24.

The plates 18 are further guided by the braces 25 and by the shank of abolt 26 which extends through the said braces and through perpendicularslots provided in said plates. These bolts 26 assist in preventing theplates 18 shifting lengthwise of the frames 19.

The plates 18 are reciprocated to and from the mandrel 15 by means oflevers 27, of which there are two, each being furnished with a handle28. The levers 27 are of the character generally termed bell-cranklevers, and the short arm 29 thereof is attached by means of a pivotscrew 30 to one of the plates 18. To permit the movement of the screw 30through outer brace 25 a curved slot 81 is provided in the said brace.

The smoothing blades 16 are adjustable fastening bolts 37 extend.

hollow angles being turned on the plates 18, each of the smoothingblades being provided with an elongated slot 32 through which the shanksof the screws 17 extend. V

s seen best in Figure 4-Of the drawings,

the screw 17 extends beyond the plate 18 toform in conjunction with thebraces a stop for determining the retracted position of the plates 18.This position is shown best in Figure 2 of the drawings, where the headof the screw 17 is disclosedas bottomed in a recess 33 in the brace 25.

The blanks shown in Figure 10 of the drawings are disposed under themandrel 15 and above the blades 16, the blades 16 being retracted toleave a clearway below the said mandrel, seen best in Figure 2 of thedrawings. l I

The position of the flat metalis regulated by: the gages 3 1. The gages3a are movably attached to extended brackets The brackets are eachprovided with a lengthwise slot 86. through which the shank of Thesebolts are employed for determining the position of the gages 3 L.

As seen. best in Figure 1 of the drawings, the gages 3 1- arerectangular in shape, the toward each other to receive the lateralcorners of the blank shown in Figure 1.0. r

lVith the mechanism constructed and arranged as above disclosed, theoperation of curling the blank shown in Figure 10 to form the spoutshown in Figure 9 is as follows: Thev blanks are successively fed to themechanism by placing the blanks within the gages 3 1, to; rest on thesupport 38 in the said gages. The operator then grasps the handles 28-and moves them from the position-shown in Figures 1 and 2 of thedrawings to the. position shown in Figure 3. This closes the blades 16on the blank to hold the same between the said blades and the saidmandrel at opposite sides of the said mandrel. The handles are thenswung from the position shown in Figure 4: to the position shown inFigure 5. The levers 27, of which the handles 28 form a part, and theparts associated therewith including the blades 16, are swung around theaxes of the mandrels 15 and 21,. with the result that the metal blankshown in Figure 10 is curled to the form shown in Figure 9, closelyhugping the mandrel15. In the final operation,

the lapped seam shown in Figure 9 is accomplished by rocking both leversand parts associatedtherewith around the mandrel 15 and partially formedspout thereon in the direction in which the outer layer of: the seam. isfolded. V

Having thus shaped the blank into the spout, the. handles 28 and partsassociated therewith are returned to the original position disclosed inFigures 1 and 2 of the drawings, when a succeeding blank is placedwithin the gages 34: and the operation repeated.

It is obvious that the operation performed by means of this mechanism isvery rapid.

The spouts formed by the present machine vary in length and diameter, asshown by a contrast of the spout C indicated in Figures 7 and 8 with thespout B shown in Figures 3 and 9. When making the spout C it is obviousthat room must be provided in line with the mandrel 15 and in frontthereof for the removal of the said spout. This is accomplished byproviding the lay mandrel 39, which is slidably held in the head 22. Tosecure the mandrel 39 in the head 22 the said head has an extendedflange 40 wherein bayonet slots a1 are provided to engage pins 12.extended from the mandrel;39. To facilitate the operation of the mandrel39, handle bars as are provided whereby the said mandrel may be quicklyadjusted to service position. To assist the elongated mandrel 15 and tosteady the same during the operation, the mandrel 39. has a centeringpin n the end of which enters a shallow socket in the said mandrel15 orwithin the pocket formed by the contracted end of the spout G. In eitherevent,

the free end of the .mandrel 15and spout being formed thereon aresupported and steadied during the operation of curling the blank.

While the mechanism-has been shown and described as forming taperedspouts, it will be understood that when desired cylindrical tubes mayalso be constructed by the mecha- Claims.
